Abstract:
This dataset contains calculated fluxes of CH4 and CO2 from surface waters in September 2021 in Swiss Cheese Lake in the Mackenzie Delta, Northwest Territories, Canada. We measured surface water gas concentrations from a small boat using a closed loop chamber and a Microportable Greenhouse Gas Analyzer (Los Gatos Research). The measurements were part of the "Mackenzie Delta Permafrost Field Campaign" (mCan2021) within the "Modular Observation solutions for Earth Systems" (MOSES) program.
